The external fund manager backed by Berkshire Hathaway's Charlie Munger, Li Lu, makes no bones about it when he says 'The biggest investment risk is not the volatility of prices, but whether you will suffer a permanent loss of capital.' So it might be obvious that you need to consider debt, when you think about how risky any given stock is, because too much debt can sink a company. We note that Arq, Inc. (NASDAQ:ARQ) does have debt on its balance sheet. But the real question is whether this debt is making the company risky.
When Is Debt A Problem?
Debt and other liabilities become risky for a business when it cannot easily fulfill those obligations, either with free cash flow or by raising capital at an attractive price. Ultimately, if the company can't fulfill its legal obligations to repay debt, shareholders could walk away with nothing. However, a more usual (but still expensive) situation is where a company must dilute shareholders at a cheap share price simply to get debt under control. Of course, plenty of companies use debt to fund growth, without any negative consequences. When we think about a company's use of debt, we first look at cash and debt together.
What Is Arq's Debt?
As you can see below, at the end of September 2025, Arq had US$25.5m of debt, up from US$17.8m a year ago. Click the image for more detail. On the flip side, it has US$7.03m in cash leading to net debt of about US$18.4m.
How Healthy Is Arq's Balance Sheet?
We can see from the most recent balance sheet that Arq had liabilities of US$39.8m falling due within a year, and liabilities of US$21.0m due beyond that. Offsetting these obligations, it had cash of US$7.03m as well as receivables valued at US$14.4m due within 12 months. So it has liabilities totalling US$39.4m more than its cash and near-term receivables, combined.
Arq has a market capitalization of US$153.7m, so it could very likely raise cash to ameliorate its balance sheet, if the need arose. However, it is still worthwhile taking a close look at its ability to pay off debt. The balance sheet is clearly the area to focus on when you are analysing debt. But ultimately the future profitability of the business will decide if Arq can strengthen its balance sheet over time.

Over 12 months, Arq reported revenue of US$118m, which is a gain of 7.2%, although it did not report any earnings before interest and tax. We usually like to see faster growth from unprofitable companies, but each to their own.
Caveat Emptor
Importantly, Arq had an earnings before interest and tax (EBIT) loss over the last year. Indeed, it lost US$983k at the EBIT level. Considering that alongside the liabilities mentioned above does not give us much confidence that company should be using so much debt. Quite frankly we think the balance sheet is far from match-fit, although it could be improved with time. However, it doesn't help that it burned through US$46m of cash over the last year. So suffice it to say we consider the stock very risky. The balance sheet is clearly the area to focus on when you are analysing debt. However, not all investment risk resides within the balance sheet - far from it.
